Simple JPA qui marche Pas !

Version imprimable

- Base donnée démarrée, (MySQL)
- Bean sérialisé avec les Annotations
- Persistence.XML bien configuré !

Avec une Classe JAVA (main() ) j'arrive pas à
dépasser le Pont JPA !

ça bloque en throwant l'exception suivante :

org.apache.openjpa.persistence.ArgumentException

Si qlq un a une idée !!

Ceci est le fichier persistence.XML

import

Fais voir ta classe java perstistante ?
t'es sur que tu utilise l'annotation javax.persistence.Id ? vérifie tes import, ca m'etonnerait pas qu'il y ait un
import ...openjpa.Id

est faite pour fonctionner avec HIBERNATE comme moteur JPA. A ce que j'ai vu apres tu utilises openjpa

Tu as donc deux possibilites

1 - soit tu passes à hibernate ( chose que je ne saurais trop te conseiller )
2 - Soit tu configures correctement le persistence-unit avec ce genre de config :

        -->

            <property name="kodo.jdbc.MappingDefaults" value="jpa(ForeignKeyDeleteAction=restrict,JoinForeignKeyDeleteAction=restrict)"/>
        </properties>
    </persistence-unit>

En esperant que ca puisse t aider
